Understand reference types

When you add an element reference to an element hierarchy the exact relationship between the referenced element and the element to which you add it depends on the type of reference. PI AF provides three system-defined reference types:

• Parent-Child

• Composition

• Weak Reference

You can also create your own custom reference types, as described in Creation of custom reference types and Child templates.
